I will be uusing Optilens for the first time and man I am scared that I'll mess coating the lenses up, hey but that's for another thread. My question is: Is 40° to cold for proper application of Optilens?
Thanks Steve

Anyone?

I don't think I've ever applied it that low. It's going to take longer to flash, which Opti-Lens seems to do anyway.

You have applied other coatings? Opti-Lens is more like OC 2.0 than Gloss-Coat, so you do need to be careful not to get any high spots.

I would say 40F is too cold to apply any kind of coating.

40F, my thermometers don't go that low,we jump for joy when it makes it down in the 50s. I don't have any info regarding your question but if I were to guess,I would say wait til it warms up,or get a halogen work light & shine it on the area for a short while,warm in no time & may help cure time. My .02 worth.

Thanks for ALL your suggestions. So halogens put off heat?

Oh yeah they do. Put your hand in front of one after it has been on for a minute or so. 350-400F measured with an infrared temp sensor. Some get even hotter,the bigger the hotter! But they are a good source of constant heat & light. I use them to help paint dry on the rare days it is cold down here & the project has to get done.

60-90 is recommended I believe.

Wow thanks, I have a work light from HD and I just never payed attention.

The main reason I stopped using halogens was due to the heat output. That's not a bad idea for the northern folks in colder temps this time of year, Whitewater!
